These are the tools that are absolutely required to build and develop KDE software. On Linux, they will typically be provided by your distribution. On other platforms, packages should normally be available, often for download directly from the home page for the tool. Of course, the standard development tools, such as a C/C++ compiler and some sort of text editor, are also required.

; CMake

+

: [[Development/CMake|CMake]] is KDE's build system of choice. Once you have this, you can use it to configure a software project for building, and that process will tell you of any other requirements you are missing.

+

+

; Git

+

: Most KDE projects are developed in [http://techbase.kde.org/Development/Git Git], and so you will need it to get the source code in the first place. You can find the relevant Git URLs at the [http://projects.kde.org/ KDE projects directory]. It will be helpful to follow the [[Development/Git/Configuration|git configuration instructions]].

: [[/Valgrind|Valgrind]] helps to find memory leaks and uninitialized memory blocks. Additional features are a profiler and more. Valgrind is one of the most important development tools!

+

: [http://userbase.kde.org/Lokalize Lokalize] is a computer-aided translation system that focuses on productivity and quality assurance. It has components usual for CAT tools: translation memory, glossary, and also a unique translation merging (synchronization) capability. It is targeted for software translation and also integrates external conversion tools for freelance office document translation.

−

: [http://kbabel.kde.org/ KBabel] is a set of tools for editing and managing gettext PO files. Main part is a powerful and comfortable PO file editor which features full navigation capabilities, full editing functionality, possibility to search for translations in different dictionaries, spell and syntax checking, showing diffs and many more.

+

−

+

−

: Also included is a "Catalog Manager", a file manager view which helps keeping an overview of PO files. Last but not least it includes a standalone dictionary application as an additional possibility to access KBabel's powerful dictionaries. KBabel will help you to translate fast and also keep consistent translations.
